Definitions

Lifting barriers such as those that protect level crossings, are less resistant than safety barriers made of concrete walls or beams metallic, so that in the event of an accident, even a light vehicle can pass through it lifting barrier and leave the roadway, while the safety barriers are precisely installed to oppose such a crossing which can be extremely serious.
the temporary passage is pre-existing, since it is a breach, and the closure of this passage cannot be a block of concrete which could ideally block the passage by restoring the continuity of the wall.
the end of the metal rails is thicker in front of the walls and forms a dangerous obstacle that we are trying to minimize by making this end smooth a curved shape by bending towards the wall.
the sliding segments are generally confined safety barriers formed entirely of metal rails because, then, the Sliding segments are themselves heald segments.
Such a barrier is described in document DE-A-2.602.014 which relates to a barrier security can be crossed by a temporary opening made by pivoting at least one barrier segment of the barrier.
each boom segment covers the end upstream of the neighboring downstream boom segment, which is described in the document above on page 7, lines 9 to 18.
the pivot according to which the heald segment is articulated is located not at a end of the pivoting segment but at a distance from this end at least equal to the overlap length.
the standards require that in the event of the barrier being struck by a vehicle, the beams must remain at approximately the same height so that they fit in the vehicle body in order to create a guide, the arm constituting a kind of flexible strap (but not elastic).
the present invention proposes a solution very different from those known, which reconciles the functional necessities of the barrier with the facilities provided by an opening formed by pivoting at least one heald segment articulated along a vertical axis.
the invention relates to a safety barrier intended to be placed along of vehicle traffic lanes, of the type comprising a fixed part and a part mobile to provide a temporary passage for vehicles, the fixed part being formed of beams parallel to the ground subject to supports each comprising a on the one hand a vertical post stuck in the ground and on the other hand of the connecting pieces of the beams to the post, while the movable part is formed of at least one leaf constituted by a movable heald segment articulated along a vertical axis, characterized in that a segment of mobile heald is directly connected to a fixed heald segment by a vertical pivot located in rear of the heald segments and away from any support.
Figure 1 is a partial schematic view of a safety barrier according to the invention, shown in elevation in front of a part provided with two leaves in position closing.
Figure 2 is a partial schematic view of the barrier of Figure 1, shown in plane, the leaves being in the closed position.
Figure 3 is a view similar to that of Figure 2 of an embodiment of the invention adapted to temporary wide passages, provided with two leaves shown in an intermediate position between closing and opening.
Figure 4 is a partial schematic view of a safety barrier according to the invention showing the rear face of a heald at the location of a joint between a fixed heald segment and a mobile heald segment.
Figure 5 is a partial schematic view showing a movable heald segment located in upstream of a temporary passage, in an intermediate position between closing and the opening.
Figure 6 is a partial schematic view showing a movable heald segment located in downstream of a temporary passage, in an intermediate position between closing and the opening.
Figure 7 is a schematic cross-sectional view of a safety barrier according to the invention, showing a joint when a movable heald segment is in fully closed position.
Figure 8 is a schematic cross-sectional view of a safety barrier according to the invention, showing a joint when a heald segment is in fully open position, 180 °.
Figure 9 is a schematic sectional view showing the reinforcement of the pieces of connection of the arm to a post close to a mobile part, to increase its resistance to stresses due to the maneuvers of a mobile segment.
a safety barrier of the type composed of supports fixed to the ground and a continuous rail formed by profile segments metal placed end to end with partial overlap.
the invention is also applicable to safety barriers of another type: concrete wall, wooden rails, etc. and of course with the metal beams which are associated over short distances with low walls concrete.
a barrier according to the invention here comprises supports each comprising on the one hand a vertical post 1 firmly fixed to the ground, for example by fitting it into a block of buried concrete, and on the other hand a spacer 3 by which heald segments 2 a , 2 b , 2 c , ... are secured, a spacer known in practice under the name of "spacer”.
a fixed barrier of indefinite length is thus constituted and provision is made, from place to place, through passages formed by movable parts of the continuous beam.
two heald segments 10 and 11 are pivotally mounted along vertical axes of articulations designated in FIGS. 1 to 3 by the global references 20 and 30, near the ends of the fixed segments 2 b and 2 c .
the movable segments 10 and 11 constitute leaves which can open like a double leaf door, as shown by the visible arrows F1 and F2 in figure 2.
vertical posts 12 and 13 of the “erasable” type are provided, that is to say likely to be moved or removed so as no longer to constitute an obstacle to the passage of vehicles when the leaves 10 and 11 are in the open position.
One solution is to place sheaths (not visible in the drawing) in the ground, the top is flush and into which the posts 12 and 13 penetrate. In the active position the posts 12 and 13 are kept vertical by the sleeves while in position erasure they are removed.
Another solution is to articulate the vertical posts 12 and 13 by their base, at the ground level, so that they can occupy either an active position in which they are erected vertically, i.e. an erasing position in which they are lowered to the ground level, possibly in notches (not shown).
connection between the spacer 3 and the post 1 must remain standard in order to keep unchanged characteristics with regard to disconnection at the support considered automatic spreader 3 and post 1 on the one hand, and against the calibrated bending of the post 1 which must be strictly similar to that of all the other posts 1 of the fence.
the number of supports is chosen according to the width of the passage temporary considered, i.e. depending on the length of the leaves, and is not in no way limited to the two supports 12 and 13 described and shown here diagrammatically.
handles 14 and 15 are provided near the free edges of leaves 10 and 11 on their face opposite to the traffic lane.
the opening maneuvers are carried out by a single man who can easily release the fastening members of the leaves 10 and 11 to the vertical posts 12 and 13 then remove or lower these posts 12 and 13, then rotate the leaves 10 and 11 using the handles 14 and 15.
the closing operations are carried out exactly the opposite of the opening operations and do not require no more effort.
the leaves 16 and 17 rest on rollers 18 and 19 of any known type, which have been shown here very schematically as having their axis plumb with the leaf which they support but which could also be mounted on a swiveling axis in screeds offset backwards, that is to say located mainly or entirely on the side of the side of the leaves opposite the track circulation, this to prevent the rollers from protruding in front of said leaves.
tracks A and B can be arranged in a centered arc on the vertical axis of joints 20 and 30.
Such a raceway is useful on uneven, grassy or sloping ground but is superfluous on a level and horizontal concrete floor for example.
the material provisions of the site hamper the folding of the leaves against the rear face of fixed heald segments, in particular because there is an obstacle on the path of a leaf or even of the two leaves, which is the case when the beams are find at a distance from an obstacle (another smooth for example) lower than the length of a leaf.
each leaf can be made up of at least two elements, or segments, articulated together like blinds or accordion shutters.
One of these so-called “basic” elements is articulated to a fixed heald segment, like the leaf 10 or like leaf 11, and the one or the first of the others is articulated to the base element or the previous element.
the continuity of the healds is ensured when the leaves 10 and 11 (or 16 and 17) are in the closed position.
the different heald segments are fixed to each other and to the supports vertical in such a way that, with reference to the normal direction of movement of the vehicles, the downstream end of each segment covers the upstream part of the next downstream segment.
the vertical axes of the articulations 20 and 30 are offset relative to the adjacent vertical edges, on the one hand of the fixed segments 2 b and 2 c and, on the other hand, leaves 10 and 11 (or 16 and 17), in order to create extensions which must cover part of the neighboring segment (fixed or mobile) when the leaves are closed.
leaves 10 and 11 are placed and fish scales, exactly as if they were fixed boom segments, taking into account the direction of traffic normal vehicle indicated by arrow F.
the articulation 30 is situated below the downstream vertical edge 2 e of the fixed heald segment 2 c situated immediately upstream of the temporary passage, which leaves an extension 2 f of length L1 which overlaps the upstream vertical edge 11a of the leaf 11 located downstream of the segment 2 c (17 and 17a for the embodiment of Figure 3), and which extends over a length of this flap 11 is substantially equal to L1, when the latter is in the closed position.
FIG. 2 it is seen that the hinge 20 is located below the downstream vertical edge 10a of the leaf 10 located downstream of the temporary passage, thereby leaving an extension 10b of length L2 which covers the upstream part of the downstream fixed heald segment 2 b , in particular its upstream vertical edge 2 q , segment 2 b itself located downstream of the leaf 10 (16 for the embodiment of FIG. 3).
the extension 10b extends over a length of this segment 2b substantially equal to L2, when the leaf 10 is in the closed position.
the lengths of the leaves 10 and 11 are uneven, in the sense that the upstream leaf 11 also has a downstream end extension 11 b which covers the upstream vertical edge 10 c of the downstream leaf 10 and which extends over this leaf 10 when the two leaves are in the closed position.
a fish-scale structure is therefore obtained from upstream to downstream of the closed temporary passage: extension 2 f on the downstream leaf 11, extension 11 b on the downstream leaf 10, extension 10 b on the downstream segment 2 b .
the leaves 10 and 11 are moved at an angle of more than 90 ° so that they are completely erased behind the fixed part of the arm.
pivot angle is greater than 90 ° and even close to 180 °.
This passage is therefore equal to the distance between the opposite ends of the segments 2b and 2c , minus the length of the extension 10b .
the movement of the leaves 10 and 11 must be greater than 90 °, at least as far as the downstream leaf 10 is concerned, but preferably, the leaves 10 and 11 can be folded back 180 ° against the face of the fixed heald segments 2 b and 2 c opposite the normal vehicle traffic lane, in the position shown in dotted lines in FIG. 2.
the joint is fixed directly to the corresponding beam (segment fixed 2 or leaf 10-11 or 16-17) and not to a vertical post 1.
the posts 1 are absolutely standard, of equal resistance all along the security barrier, so that a vehicle accidentally striking this barrier meets the same resistance calibrated, whether it is far from the hinged leaves, near the hinged leaves or on the articulated leaves.
the length of the leaves 208-210 and 207-208 is such that the pivot 211 is moved away from the fixed heald segment 2b and from the leaf 10 to allow the latter to pivot at an angle of 180 °, until it is practically applied against the rear face of the fixed heald segment 2 b .
One or more stops can be provided on the rear face of the fixed heald segments and immobilization means to prevent any accidental movement of the leaves 10 and 11 open.
the reverse maneuvers are carried out, starting with the leaf 11, so that the end of the leaf 10 is found behind the extension 11 b .
Each stiffener comprises a part 4 a secured to the spacer 3 and two wings 4 b and 4 c secured to the heald segment 2.
the weight of the articulated movable part when it is no longer in the closed position, does not tend to excessively twist the fixed heald segment 2 which supports it and does not of consequence on the mechanical characteristics of this segment 2.
Another reinforcement solution is to provide a greater number of supports vertical 1-3 because the assembly is more rigid and more resistant, even if each support 1-3 is the same type as the others.
